  <description>
    <p>
    Stefan Esser discovered a vulnerability in the code of the neon library :
    if a malicious date string is passed to the ne_rfc1036_parse() function, it
    can trigger a string overflow into static heap variables.
    </p>
  </description>
  <impact type="normal">
    <p>
    Depending on the application linked against libneon and when connected to a
    malicious WebDAV server, this vulnerability could allow execution of
    arbitrary code with the rights of the user running that application.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time. All users are advised to upgrade
    to the latest available version of neon.
    </p>
  </workaround>
  <resolution>
    <p>
    All users of neon should upgrade to the latest stable version:
    </p>
    <code>
    # emerge sync

    # emerge -pv ">=net-misc/neon-0.24.6"
    # emerge ">=net-misc/neon-0.24.6"</code>
